Dodge Durango (HB). Manual — part 356
PANEL LAMPS DIMMER CIRCUIT
NOTE: As part of the exterior lighting failsafe feature, upon ignition On all of the panel lamps dimmer circuit
lamps will illuminate at full intensity and the exterior park lamps and headlamp low beams will illuminate
regardless of the headlamp switch position if the instrument cluster cannot detect an input from the head-
lamp switch, or if there is a loss of data bus communication.

AJAR SWITCH
DESCRIPTION
DOOR
This vehicle has four door ajar switches, one for each door. Each switch is concealed within and integral to its
respective door latch unit. The switches are momentary leaf contact-type units that are actuated by the mechanisms
internal to the door latch. A short pigtail wire and connector on each door latch connects the door ajar switch to the
vehicle electrical system through its respective door wire harness. The door ajar switches cannot be adjusted or
repaired and, if faulty or damaged, the door latch unit must be replaced. (Refer to 23 - BODY/DOOR - FRONT/
LATCH - REMOVAL) or (Refer to 23 - BODY/DOOR - REAR/LATCH - REMOVAL).
LIFTGATE
A liftgate ajar switch is standard equipment on this vehicle. The switch is concealed within and integral to the liftgate
latch unit. The switch is a momentary leaf contact-type unit that is actuated by the liftgate latch mechanisms. An
integral connector receptacle on the liftgate latch connects the liftgate ajar switch to the vehicle electrical system
through the liftgate wire harness. The liftgate ajar switch cannot be adjusted or repaired and, if faulty or damaged,
the liftgate latch unit must be replaced. (Refer to 23 - BODY/LIFTGATE/LATCH - REMOVAL).
OPERATION
DOOR
The door ajar switches are actuated by the mechanisms internal to the door latch. When a door is closed and
properly latched, its door ajar switch is an open circuit. When a door is open or only partially latched, the door ajar
switch is a closed circuit. The rear door ajar switches are hard wired in series between a body ground and the
ElectroMechanical Instrument Cluster (EMIC). On vehicles not equipped with the optional memory system, the front
door ajar switches are also hard wired in series between ground and the EMIC.
On vehicles equipped with the optional memory system each front door ajar switch is hard wired in series between
ground and its respective driver or passenger Memory Mirror Module (MMM) located in the front door. The MMM
then sends electronic door ajar switch status messages to the EMIC over the Controller Area Network (CAN) data
bus. Both the EMIC and the MMM read the hard wired door ajar switch inputs through internal pull-ups, then use
these inputs to control many electronic functions and features of the vehicle.
The door ajar switches can be diagnosed and tested using conventional diagnostic tools and procedures. Refer to
the appropriate wiring information. However, conventional diagnostic methods may not prove conclusive in the diag-
nosis of the EMIC, the driver or passenger MMM, the CAN data bus, or the electronic messaging used to convey
door ajar switch status to other modules in the vehicle. The most reliable, efficient, and accurate means to diagnose
the EMIC, the driver or passenger MMM, the CAN data bus, and both the hard wired and electronic message inputs
and outputs affected by the door ajar switch inputs requires the use of a diagnostic scan tool. Refer to the appro-
priate diagnostic information.
LIFTGATE
The liftgate ajar switch is actuated by the liftgate latch mechanism. When the liftgate is closed and properly latched,
its liftgate ajar switch is an open circuit. When the liftgate is open or only partially latched, the liftgate ajar switch is
a closed circuit. The liftgate ajar switch is hard wired in series between a body ground and the ElectroMechanical
Instrument Cluster (EMIC). The EMIC reads the hard wired liftgate ajar switch input through an internal pull-up, then
uses this input to control many electronic functions and features of the vehicle.
The liftgate ajar switch can be diagnosed and tested using conventional diagnostic tools and procedures. Refer to
the appropriate wiring information. However, conventional diagnostic methods may not prove conclusive in the diag-
nosis of the EMIC, the Controller Area Network (CAN) data bus, or the electronic messaging used to convey liftgate
ajar switch status to other modules in the vehicle. The most reliable, efficient, and accurate means to diagnose the
EMIC, the CAN data bus, and both the hard wired and electronic message inputs and outputs affected by the lift-
gate ajar switch inputs requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

REMOVAL
BULB
WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental
restraint system before attempting any steering wheel, steering column, airbag, occupant classification sys-
tem, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect
and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge
before performing further diagnosis or service. This is the only sure way to disable the supplemental
restraint system. Failure to take the proper precautions could result in accidental airbag deployment.
1. Disconnect and isolate the battery negative cable.
2. Remove the center bezel lamp unit (4) from the
instrument panel. (Refer to 8 - ELECTRICAL/
LAMPS/LIGHTING - INTERIOR/CENTER BEZEL
LAMP UNIT - REMOVAL).
3. Depress the latch tab (2) and slide the hood (1) off
of the end of the lamp housing.
4. Pull the base of the bulb (3) straight out of the bulb
holder within the lamp housing.

1. Disconnect and isolate the battery negative cable.
2. The center bezel lamp unit (1) is located on the
instrument panel center support structure, which
forms the roof of the center floor console forward
storage bin. Reach into the storage compartment
and use a small thin-bladed screwdriver to depress
the lamp retaining latch (4) on the end of the lamp
housing nearest the lens (3).
3. Pull the lamp down and rearward to disengage the
fixed retainer (2) from the mounting hole.
4. Disconnect the wire harness connector from the
lamp connector.
5. Remove the lamp unit from the storage bin.

CAUTION: Always use the correct bulb size and type for replacement. An incorrect bulb size or type may
overheat and cause damage to the lamp, the socket and/or the lamp wiring.
1. Align the base of the center bezel lamp bulb (3)
with the bulb holder within the lamp housing (4).
2. Push the bulb straight into the bulb holder until the
base is firmly seated.
3. Slide the hood (1) over the end of the lamp hous-
ing until the latch tab (2) snaps into place.
4. Reinstall the lamp unit into the instrument panel.
(Refer to 8 - ELECTRICAL/LAMPS/LIGHTING -
INTERIOR/CENTER BEZEL LAMP UNIT - INSTAL-
LATION).
5. Reconnect the battery negative cable.
